The camshaft is an elgin 1131 240 int 250 ext .520 with either a victor jr or an rpm air gap and i am not sure on carb yet. The car is auto transmission that will be rebuilt and probably a 3000-3200 stall. How much hood clearance trouble will i have? Also i was thinking about going with a hydraulic roller in stead of the solid flat tappet cam.
With that victor jr the hood will hit and with the air gap also. Your going to have to run a orignal style drop base for the filter with whatever you run. I ended up with a performer rpm on my 74 and the hood still hit. This was without the drop base filter base though. JMO
